I've got 3 feats that allow the PC to temporarily change the ability score a save is based on to their primary spellcasting attribute.  I setup a selector for attributes. I tried setting up a string variable that was the SaveAbil.[whatever the selected ID is] but it didn't like that and then I tried just putting the id into the statement like so and that didn't work either
	
	
	
		
Any ideas how to accomplish this, I didn't have much luck looking for examples.

	perform hero.child[svFort].tagreplace[SaveAbil.?,SaveAbil.field[usrChosen1].chosen.idstring]
